INKING APPARATUS FOR PRINTING-PRESSES.

Specification of Letters Patent.

Patented June 25, 1912.

To all whom it may concern:

' Be it known that I, VVILLIAM K. Hone- MAN', a citizen of the United States, residing at Taunton, in the county of Bristol and State of Massachusetts, have invented a new.

cating bed operates in conjunction with inkrollers to distribute the ink which is supplied to them from an ink fountain by means of a ductor roller; and the objects of my invention are, first, to provide for all of the composition ink rollers to be alike and interchangeable; second, to provide a light metal ductor roller of suitable diameter to distribute the ink rapidly and to be easily started, rotated and stopped by contacting with the composition ink rollers; third, to so arrange the parts that the ink fountain is always open and accessible and never obstructed by the ink table; fourth, to so arrange the parts that the ink table never passes through the path of the ductor roller; fifth, to provide a composition ink feed roller which is always in contact with the fountain roller and with which the ductor roller 4 before the fresh ink being transsupply of ink; sixth, to so arrangethe parts that the ink is delivered to a group of distributing rollers where it is distributed before it reaches the ink table. I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation partly in section of an inking apparatus embodying my invention, indicating the relation of the several parts in dotted lines. Fig. 2 is a top plan view of Fig. 1, partly broken.- Fig. 3 is a vertical sect-ion on line m w, Fig. 2.

Similar numbers refer to similar throughout the several-views.

In the drawingsfll designates the ink fountain roll, located substantially in the path of but beyond the reach of the ink table; 2, the composition ink feed roller which is always incontact with the fountain roller 1; and 3, the ductor roller which is parts adapted to transfer the ink from the roller 2 tothe composition ink table roller i.

The three composition ink table rollers 5 are identical in construction and purpose withthe ink table roller 4, excepting that they do not receive ink direct from the duotor roller 3. These four ink table or distributing rollers are mounted in the usual way to contact with and distribute ink'on the ink table 6 and they contact in the usual way with the usual vibrating rolle'rs 7 which continuously drive them to conform to the direction and speed of the ink table. The

vibrating rollers 7 are driven by the usual spur gears 8, 9, 10, 11 and 12, as plainly indlcated in the drawings, the gear 12 receivlng motion from the rack 13 which is reciprocated by thebed of the press in any well known manner, not shown. The vibrating rollers 7 are vlbrated 1n the usual manner by means of the vibrating arm 36 as plainly shownin Fig. 2. The fountain segment lt by mechanism, not shown, and makes one turn to each-complete stroke of the press. The fountain segment meshes with and oscillates the segment 19 which is mounted loosely beside the fountain ratchet wheel on the outer end of the fountain roller-"1. The

s'egment19 carries the usual fountain pawl 20 which operates to turn the fountain roller step by step-by, engaging the teeth of the fountain ratchet wheel 21 which is fast to the outer end of the fountain roller. The

fountain pawl 20 is controlled by a drag,

the frame of the machine, and provided with an arm 24, carrying a pin 25, connect ing the end of the connecting rod 26. The other end of the connecting rod 26 passes through the free end of the lever 27 and is reach it.

reached its nearestapproach to the ink fountain and the ductor 3 has just contacted with the distributing roller 4. Now on account of the distance from the contactingpoint of the distributing roller 4 with the ink table being farther away from its contacting point with the'ductorS than to the end ofthe ink table, none of the fresh ink fromthe ductor roller can reach the ink table during its table passes from beneath the distributing roller 4 before the fresh ink being transferred to the roller from the duct-or can Theductor remains in contact with distributing roller =4 during substantially the whole of the stroke of the ink table away from-the ink fountain and =at the be- 7 ginning of the retumstroke it moves to con- 1 tact with the composition roller 2 and stays 1n contactwith thatroller during the major part of-the returnstroke to receive a new supply of ink.

Operation: When the fountain roller 1 'is which transfers it to the distributing roller 4 from which it is taken and thoroughly distributed by the first group 0f-distributing rollers 5, 7 and 4, before it is distributed upon the ink table '6. From the inkta'ble the ink-is transferred to the second group of distributing rollers and to 'the form rollers and form, not shown, in the usual manner.

What I claimis: 1, In an inking apparatus for a bed and cylinder printing press, the combination of a reciprocating bed and ink table, a group bed and ink tableymeans for vibrating said vibrating rollers endwise, a fountain roller,

a feed roller continuously contacting with said fountain roller, and a ductor roller aldistributing roller.
